Answer: Bundles of axons in the central nervous system are called a "tract"
Explanation:
Axons(nerve fiber) consist of long slender projection of neurons or nerve cells that conduct and transmit impulses away from the neuron or nerve cell body. Axons are surrounded by endoneurium layer which contain protein fluid that surround each axon.
Bundles of axon in the CNS is known as tract. We have ascending tracts and descending tracts. The ascending tracts function are to conduct and carry impulses along the spinal cord to the brain while the descending tracts transmit and carry the impulses from the brain to lower regions (downward) of the body. Tracts are identified by their origin (where the bundle start) and also the end/termination of axon bundle.
The largest tracts are fasciculi gracilis and cuneatus which are known as ascending tracts.
The last option because it's like the earth
Unfortunately this question is incomplete as no options are provided. IN actual fact,<span> four muscles are involved in mastication. Three of these are responsible for biting down, namely the masseter, the temporalis and the medial pterygoid, whereas one, the lateral pterygoid, is responsible for opening of the jaw</span><span>. All four muscles help to move the jaw laterally.</span>
Answer:
See the answer below
Explanation:
<em>When the salt water resulting from using salt to thaw ice and snow is washed off the road, the nearby plants along the roadside would be subjected to osmotic stress due to the lower water potential of the soil water when compared to that of their cells. Consequently, the plants are expected to lose water to the surrounding salt solution until an equilibrium is established between their cytosols and the soil solution. </em>
Answer:
blind spot will not impair your vision
Explanation:
Blind spot may be defined as the point of our eyes where the optic nerve leaves our eye, which creates a "blind" spot as none of the receptor cells are located there.
A blind spot can only be studies in a laboratory because blind spot does not impair our vision. The blind spot falls on nose side of our retina, that means that the objects to our right side falls on the right eye's blind spot and objects to our left may fall on the left eye's blind spot. Thus, the blind spot normally does not impair our vision, since our eyes are moving and because our one eye catches what the other eye misses.
